I appreciate what you do for the gravity series grilling community! You build momentum and help people to be successful and extend the life and usefulness of their gravity series. You are an inventor and an ace fabricator, You make things better!

The parcel has just arrived, which is super quick by any standard—six days from the USA to New Zealand! There is also a very low freight cost. Everything looks amazing, too, and I can't wait to get it installed. It's well-designed and thought-out. I can see it's all heavy-duty and made for the purpose, so fitting it should go smoothly. It is nice to know my grill is going to perform better and last longer, too!

I think I have all the stuff you sell for the Masterbuilt 1050. Love it all. The rack and front shelf are great!

Blair R. • Kitchener, Ontario, Canada

I've done a number of cooks with the new mods and they're all excellent! Thanks again! 

Devin T • Alberta, Canada

Thanks for the quick reply. I will be purchasing soon. I already have the manifold cover and drip pan brackets. Great products!

It is extremely rare that I contact a seller that I have purchased an item from and tell them Thank You. Between placing my order, getting the shipping info and receiving the item. This has been a smooth transaction. I've heard you are a one man operation and again I just wanted to say thank you it has been a pleasure doing business with you. You always get favorable reviews on the MasterBuilt forums I am part of. I fully intend to order additional items from you.

YOU GOT A GOOD THING GOING! It worked like a dream and made life better. Forty-five minutes after I turned off, there was no smoldering in the coal bin, and I was able to cover it before the thunderstorm hit. It used to leak and take three hours to cool off.

Richard G • Tallahassee, FL

The rain stopped so I could install the new products. They are outstanding! Thanks again...

Stephen G. • Bedford TX

Still can believe i ordered after work Thursday night and it was here today! Everything looks great and fits perfectly! The sticker you sent is on the pit now and ill definitely be ordering more from you. 

Andrew G • Clinton, WI

Thank you for the quick response. I love the mods -- they have truly taken this grill to the next level.

I wanted to write about the new Super-Sear manifold. I hooked it up and finally smoked a New York Strip on Saturday, searing the outside after removing the manifold cover. It was to die for! On Sunday, thanks to you, I GRILLED bison burgers—wow—I was really missing the grilling portion of my outdoor cooking.

Stuart K • Oakland, CA

Love your mods going to order the rest of them when I get the money. Great job!!!!!!!

Keith S. • Warrensville, NC

I just wanted to let you know that I installed the cover yesterday, and I once again have a functional smoker. Thank you so much!

Dave D • Christiansburg, VA

Your products so far have performed awesome. First steaks I cooked on the grill with the new manifold turned out awesome. We had a guest over. Her boyfriend is the cook at the fanciest local establishment we have. She stated he needed to come over to learn how to cook steaks. This restaurant is known for having the best steaks around!
